What is semi continuous culture?
During semicontinuous culture, a sample of fixed volume is removed at regular time intervals to make measurements and/or harvest culture components, and an equal volume of fresh medium is immediately added to the culture, thereby instantaneously enhancing nutrient concentrations and diluting cell concentration.
What is continuous culture of algae?
Algae grown in continuous cultures are indefinitely in exponential balanced growth, poised at a particular physiological steady state, or a cyclical steady state under a light-dark cycle (cyclostat).
What are the three types of microalgae?
Microalgae include the dinoflagellates, the diatoms, and other single-celled algal species. Macroalgae include macroscopic red algae, brown algae, and green algae. Both microalgae and macroalgae are important contributors of atmospheric oxygen through photosynthesis.

What is mass culture of algae?
Algal mass culturing research has been carried out in many parts of the world for past 30 yr. The main attractiveness of algal mass cultures is that they have great versatility to be integrated into multi-use systems for simultaneously solving several environmental problems.
